Getting: "MySQL said: 'reading initial communication packet', system error: 0" when connecting through iPhone-network

  • Posted December 17, 2014

I am often getting this error:

MySQL said: Lost connection to MySQL server at ‘reading initial communication packet’, system error: 0

When I am trying to connect to my database using MySQL. But the actual server (i.e. my app) runs without issues.

It seems only to happen when I am on my iPhone’s cellular datanetwork (using internetsharing). When connected through WiFi hotspots, no errors seem to happen.

Anyone knows what could be wrong?

EDIT: I now realised that this has nothing to do with my celluar data. I am on my home WiFi hotspot now, and it does not work here either. I did a “sudo reboot”, and when trying to reconnect, it works! Why God, why?

p.s. I am using Sequel Pro to connect, and I see it succeeds to connect to SSH, but fails at MySQL connecting.

Either your server or your cellular provider is blocking port 3306.
